'Date' Column

Where exactly does Calibre get the 'Date' column data?

I watched the new "What's New in 0.7" video by Kovid, and he mentioned the 'Date' field is when the book was added into Calibre. However, I have a few books that show 'Dec 2007' as the date, even though I created and added those books into Calibre a couple weeks ago.

If I look at the file properties of the Epub, they also show a May 2010 created and modified date.

EPUB files can have metadata that causes the date to be set. For example, change the date, save an epub file using save to disk and re-add it to calibre, you should see the date being the changed date rather than the date it was added.

Ok, I saw this issue too. Is there a preference to make the date, always be the date of addition to the library.

I recently added 17 new EPUB books (recently bought from Bean Books) only to find them being listed as the oldest books books in the library.

Add a custom date_added column (CC's are a great new feature) .

There are instructions, but preferences, interface is the place to start.

Calibre won't accept the underscore.

EDIT: I was assuming using the specific name 'date_added' in the lookup field would link it to some form of an internal variable already set in the dbase.

Since the above doesn't seem to be the case, I made my own date added column, but it's blank for all the books. Is there a way to add this column so it autopopulates with the real date added?

Just double click in that column on the title row. Today's date (or type in a date)
Optionally:
highlight a bunch of records (to change )
Click the Edit Meta-data button.
Switch to the custom tab
Set the date you want ALL the selected records to have.
Done

My date column never changes from the date the file was added. My published column does if I pick metata with a published date?

I would dearly love to have an automatic downloaded copyright date but probably difficult to implement

That is a mistake, which I have fixed.
